Abstract

PROBLEM TO BE SOLVED: To realize efficient bulk connection using a representative extension, in which one trunk line number can connect many incoming calls when a bulk connection terminal capable of high speed communication interconnects a trunk line and an extension in a private branch of automatic exchange. SOLUTION: A calling setup request SETUP set in an ISDN information storage memory is converted into an incoming request extension number (S1). When the incoming request extension number indicates a bulk connection terminal (S2), whether or not there are disagreements between a required B channel and an already incoming call B channel is discriminated (S3). When there is not already received call when both disagree, a flow β is transited and a call receiving destination is decided as a new incoming call. Meanwhile, when there is an incoming call where the both are dissident, it is discriminated that there is an additional channel wait bulk connection terminal and the caller number of the already received incoming call is compared with that of this incoming call (S4-S6). When both the caller numbers agree, the call reception destination of the same extension is decided (S8, S9). The comparison in the S6 is applied to all incoming calls in an additional channel wait state.

2. Description of the Related Art Generally, in ISDN transmission, 64 bits are used.
The B channel of Kbps is one communication unit. A so-called bulk communication system, which enables high-speed communication by considering a plurality of B channels as one communication, is currently being implemented.

Conventionally, in an automatic private branch exchange (PBX), when a bulk connection terminal is connected between an office line and an extension, bulk connection using an extension representative incoming call system has been impossible.
Therefore, conventionally, in order to realize this bulk connection by PBX, a dial-in system or a sub-address has been used. Also, the procedure for capturing multiple B channels for bulk communication in a private network and negotiating the communicable speed is disclosed in Japanese Patent Application Laid-Open No. 9-284873.

In addition, if a call is made to a specific bulk connection terminal, and that terminal is busy, the caller will try again later or
If you need to call the bulk connected terminal with a different number again,
Line costs and the time and effort of callers to repeat calls have increased. In view of the above, the present invention, when connecting a bulk connection terminal capable of high-speed communication between an office line and an extension in an automatic private branch exchange, an extension representative that can connect a large number of incoming calls with one office line number An object is to realize a used and efficient bulk connection.

The present invention utilizes an ISDN caller ID notification function, and associates an extension / caller information office data memory and an I / O data memory for associating the caller ID with the required number of communication lines in the PBX.
By providing an SDN information storage memory, waiting for incoming calls of a plurality of necessary lines, and connecting to a bulk connection terminal of the destination,
It is an object of the present invention to provide a bulk connection method and apparatus of a bulk connection terminal using an extension representative group system.

Further, the present invention makes it possible to form a single representative number for a plurality of types of bulk access terminals having different required numbers of B channels, and for terminals that are not bulk access terminals, and to correspond to an originating bulk access terminal. It is an object of the present invention to provide a bulk connection method and apparatus capable of connecting to an incoming bulk connection extension having a number of B channels. It is another object of the present invention to realize an extension representative bulk connection in which the required number of B channels can be appropriately set and changed for each terminal.

Another object of the present invention is to eliminate the need to perform an operation of calling a different bulk connection terminal again when a specific bulk connection terminal is busy, and to reduce the associated line cost. I do.

TC 101 and ILC 102 are communication path switches 100
And are connected to the ISDN public network 11 and the bulk connection terminal 13, respectively. CC103 is PBX10
The whole is controlled, and the bulk connection processing according to the present invention is executed.

The MEM 104 stores various programs such as an exchange operation control program, station data, various tables, and the like. The MEM 104 includes the station data memory 105 and the I
An SDN information storage memory 106 is provided. The station data memory 105 is a memory area including data for associating the incoming B channel with the already received one. The station data memory 105 further includes an extension station data memory 11.
1 and a caller information office data memory 112.

FIG. 2 is an explanatory diagram of the extension station data memory 111. The extension station data includes an extension number and a bulk terminal class. The extension number is a number corresponding to the bulk connection terminal 13 accommodated in the PBX 10. The bulk terminal class is a class of a terminal to be bulk-connected.
In the embodiment illustrated in FIG. 2A, the bulk terminal class is indicated by, for example, the number of B channels (eg, 1B, 2B, 3B, 1, 2, 3, etc.) that can perform bulk communication. In this figure, extensions A and B are bulk connection terminals capable of performing bulk communication on two B channels.
Extension C is a bulk access terminal that can perform bulk communication on three B channels. The extension D is a terminal that is not a bulk connection terminal and communicates on one B channel.

FIG. 2B shows another embodiment of extension station data. As shown in this figure, the extension station data can include data indicating whether or not the terminal is a bulk communication terminal. Here, as an example, the bulk flag (0, 1) and the number of B channels (1, 2, 3, etc.) are shown. In this figure, extensions A and B indicate that they are bulk access terminals because the bulk flag is “1”, and that the number of B channels is “2”, so that the bulk communication is performed using two B channels. It shows what you can do. Extension C is a bulk access terminal that can also perform bulk communication on three B channels. The extension D indicates that the terminal is not a bulk connection terminal because the bulk flag is “0”, and the number of B channels is “1”.

FIG. In the embodiment of FIG. 3A, the caller information station data includes a caller number, the number of necessary communication channels (B channels), the number of already received B channels, and the extension number of the called party. The caller number and the number of necessary B channels corresponding thereto are set in advance. The number of already received B channels and the extension number are set for each incoming call. The extension number of the bulk connection terminal is stored in the called extension number area when a called party is determined when answering a new incoming call. The number of received B-channels area indicates the following B for the bulk connection of the received call.
When a channel is determined as a destination, it is added and rewritten.

FIG. 3B shows another embodiment of the sender information station data. Here, the caller information station data includes data indicating whether or not an incoming call is being received (an incoming call flag), and data indicating whether or not an incoming call of the next communication channel is waiting for addition for bulk connection ( Add wait flag) etc.
It can be included as appropriate. The additional waiting flag can be determined, for example, based on whether the number of already-received B channels and the required number of B channels do not match or match.

In this figure, the terminal having the caller number a has the incoming call flag of "1", indicating that the terminal is receiving an incoming call. Since the addition waiting flag is "0", it indicates that the terminal is not waiting for addition. It is. That is, it indicates a state in which the destination has been determined or can be determined. Also, the required number of B channels is “2” and the number of already received B channels is “2”.
2 'indicates that the destination has been determined or can be determined from now on. The incoming extension number is determined to be “A”. Also, caller number b
With regard to, it is known that the incoming call is being received because the incoming call flag is “1”, and the addition waiting flag is “1”, indicating that it is waiting for addition. That is, it is determined that it is in a state of waiting for the arrival of the next B channel. Further, since the required number of B channels is “2” and the number of already received B channels is “1”, it is shown that the bulk connection is to be performed by two B channels waiting for another B channel. It is. The extension number of the incoming call has not been determined yet. For the caller number c, the incoming call flag is set to '
Since it is 0, it is known that no incoming call is being received, and the addition wait flag is also 0, indicating that it is not waiting for addition. It is also indicated that this terminal is a bulk connection terminal whose required number of B channels is '3'. Note that the terminal of the caller number that is not the bulk connection terminal has the required number of B channels set to “1”.

FIG. 4 is an explanatory diagram of the ISDN information storage memory 106. The ISDN information is transmitted from the ISDN public network 11 or the bulk connection terminal 13 connected to the PBX 10. The received ISDN information is the ITC 101
Alternatively, it is stored in the ISDN information storage memory area corresponding to the ILC 102. This figure shows a data configuration of a memory that stores ISDN information received from the ISDN public network 11. Here, the ISDN information storage memory 106 stores ISDN information including a call setup request (SETUP) including a caller number and a callee number.

FIG. 5 is an explanatory diagram of SETUP set in the ISDN information storage memory 106. This figure shows the PB
X10 is call setting request information received from the ISDN public network 11. Here, as an example, a configuration of SETUP including information elements for specifying a caller and a callee is shown. The SETUP includes a calling number information element and a calling sub address information element as a calling party number, and a called number information element and a called sub address information element as a called party number.

FIG. 6 is an explanatory diagram of another embodiment of the ISDN information storage memory 106. As shown in FIG. 6A, the ISDN information storage memory 106 has
When responding to an incoming call, in addition to the caller number and the callee number, the caller information station data should also include appropriate information on the number of necessary B channels, the number of already received B channels, and the extension number of the call. Can also. Further, as shown in FIG. 6B, the ISDN information storage memory 106 may appropriately include an incoming call flag indicating whether or not an incoming call is in progress, an additional waiting flag, and the like, similarly to the sender information station data. Can be. In this case, in each process, the ISDN information storage memory 10
6 may be used, or the data of the caller information station in the station data memory 105 may be used. Further, data corresponding to the above-mentioned sender information station data is stored in the ISDN information storage memory 106.
You may make it memorize | store only inside.

Next, the operation of the incoming call control of the bulk connection terminal in the PBX 10 will be described.

FIG. 7 shows an incoming sequence diagram of the bulk connection. This figure shows that the bulk connection terminal 13 (D) transmits a call and the PBX 10 responds to the incoming call.
3A shows a sequence of ISDN information when performing bulk communication with FIG. In the figure, between the bulk access terminal 12 and the ISDN public network 11, the ISDN public network 11 and the PB
X10, and between the PBX 10 and the bulk connection terminal 13
The transmission and reception of each signal between and are shown. Here, the number of necessary B channels for bulk connection is assumed to be two channels as an example.

First, a call is made from the bulk connection terminal 12 to the bulk connection terminal 13 accommodated in the PBX 10 to use the B1 channel. The call setup is started by sending a call setup request (SETUP) from the caller, and a notification (CALL PR) indicating that the call setup is being processed.
After the transfer of the OC), the calling of the called terminal is started, and the fact that the called party is calling is notified (ALERT). Therefore, the bulk connection terminal 13 accommodated in the PBX 10
Responds to the incoming call by saying that the called party has answered (CO
NN) is sent to the caller, and the B1 channel is being communicated. As the sequence at this time, a standard outgoing / incoming sequence of ISDN can be used. Note that the response confirmation (CONN ACK) is a confirmation for CONN. Further, transmission of CALL PROC, CONN ACK, and the like may be optional as appropriate.

Next, in order to use the B2 channel following the B1 channel, the B2 channel is set to be in communication according to the same sequence as that for the B1 channel. After that, both the B1 and B2 channels are used, and image data communication and the like are performed by bulk communication.

FIG. 8 shows a flowchart of the bulk connection process. This is a flowchart showing the procedure of the incoming connection control processing of the bulk connection, and is executed by the CC 103 when the PBX 10 receives SETUP.

First, in step R1, the PBX 10
Indicates that when an incoming call is received,
SETUP which is N information is received. In step R2, the SET including the received calling party number and called party number
The UP information is written into the ISDN information storage memory 106, and an incoming call is set (call setting step). Step R
At 31, a destination corresponding to the incoming call is searched and set. The details will be described later.

After the destination is determined, it is determined in step R32 whether all the required number of B channels have been received (third determination step). If it is determined that all the required B channels have not been received, the process returns to step R1 to prepare for the arrival of the next B channel. On the other hand, if it is determined in step R32 that all the required B channels have been received, it is determined in step R4 whether or not the incoming call is possible as a result of the search. Here, if there is no destination, it is determined that
In step R7, the destination public busy network 11 performs a process of receiving an incoming call. On the other hand, if it is determined in step R4 that it is possible to receive a call, in step R5, a CALLPROC is transmitted to the ISDN public network 11 to indicate that it is possible to receive a call and that processing is in progress.
Further, in step R6, SETUP, which is ISDN information, is transmitted to the bulk connection terminal 13 accommodated in the PBX 10, and an incoming call by bulk communication is connected to the held extension (connection step).

After the SETUP transmission, the bulk communication can be performed as in a normal ISDN reception sequence as shown in FIG. Note that the order of steps R5 and R6 may be reversed. In this way, the PBX 10 connects the bulk connection extension 13 when the last B channel arrives in the case of bulk communication.

FIG. 9 shows a flowchart of the destination search processing of the bulk connection terminal. This corresponds to step R in FIG.
3 shows a procedure of a destination search process. In the present invention, the incoming call destination search processing enables incoming call control to a bulk connection terminal that has formed an extension representative.

First, in step S 1, each bulk connection terminal 13 is set by setting the PBX 10 based on the SETUP called party number set in the ISDN information storage memory 106.
Convert to the extension number assigned to. Step S
At 2, it is checked whether the called extension terminal is a bulk connection terminal. That is, the extension station data memory 111 corresponding to the converted extension number is referred to, and it is determined whether or not the incoming call is bulk communication based on a bulk terminal class (or a bulk flag or the like) in the extension station data (first). Judgment step).

Here, when it is determined that the connection is not the bulk connection, the flow shifts to the flow α. FIG. 10 shows a flow α, that is, a flowchart of a destination search process that is not a bulk connection. In the flow α, first, in step S810, it is checked whether there is an available channel that can receive a call. If there is no available channel that can be received, step S8
At step S11, a busy process is performed and the flow is terminated. On the other hand, when there is an available channel that can receive a call, a process of determining a destination is performed at step S809, and the flow is terminated.

If it is determined in step S2 that the extension number for which there is an incoming call request is a bulk connection terminal, then in step S3, the number of required B channels does not match the number of already received B channels. It is determined whether there is an incoming call (second determination step). Specifically, the caller information office data memory 112 or the ISDN
With reference to the information storage memory 106, the incoming call is determined based on one or more of the already-received B channels or the presence / absence of the incoming flag. Further, referring to these memories, the number of required B channels is compared with the number of already received B channels, or an additional wait flag indicating whether the number of incoming B channels and the required number of B channels do not match or matches is used. Thereby, the waiting state for the additional channel can be determined.

If it is determined in step S3 that there is no incoming call waiting for an additional channel, the process proceeds to flow β. FIG. 11 shows a flow β, that is, a flowchart of a destination search process for a new incoming call. The flow β is a process when a bulk connection to a new extension number is requested. First, in step S910, the bulk connection terminal checks whether there is a free extension for the required channel in the representative group. If there are extensions for the required channels, step S9
08, the caller information office data memory 112 and / or I
The current incoming call is written to the SDN information storage memory 106. This writing is performed by, for example, adding to the number of already-received B-channels or setting a flag to an additional waiting flag and an incoming call flag. Next, step S909
To determine the destination as an incoming call to the new bulk connection terminal, and caller information station data memory 112 and / or I
The incoming extension number of the SDN information storage memory 106 is written. If it is determined in step S910 that there is no available extension for the required channel, an extension busy process is performed in step S911, and the flow ends.

On the other hand, if there is a mismatch between the required number of B channels and the number of received Bchs in step S3, it is determined that the searched extension terminal is a bulk connection terminal waiting for an additional channel. In this case, in step S4, the caller information station data memory 112
Alternatively, the caller number is extracted from the ISDN information storage memory 106. Also, in step S5, the ISDN
For a call received from the public network 11, the caller number of the current incoming call set in the ISDN information storage memory 106 is extracted. Then, in step S6, a comparison is made between the caller ID and the caller ID of the incoming call and the current incoming call. In this case, the caller ID is the calling number information element,
Alternatively, both the calling number information element and the calling subaddress information element can be used as appropriate.

If both caller numbers match in step S6, in step S7 the destination is identified as the current incoming call and the already-received call are from the same bulk connection terminal 12. The number of received B channels in the caller information station data memory 112 or ISDN information storage memory 106 corresponding to the caller number is added and rewritten (rewrite step). Note that the addition wait flag can be further rewritten as necessary. Next, in step S9, the destination of the current incoming call is determined to the same extension number as the already-received call (first determining step).

On the other hand, if it is determined in step S6 that both the caller IDs do not match, then in step S7, the number of necessary B channels and the number of already received B channels do not match (ie, waiting for an additional channel). The received call is stored in the caller information office data memory 112 or the ISDN information storage memory 1
It is determined whether the total number has been checked by referring to 06 (determination step).

If it is determined in step S7 that the total number has not been checked, the processing is repeated from step S3 again (repeated step). On the other hand, if it is determined that all the calls have been checked, the flow shifts to flow β and the incoming call processing is performed as a new incoming call. That is, if there are available extensions for the required number of channels (step 910), the incoming call is written in the caller information station data memory 112 and / or the ISDN information storage memory 106 (step S908), and the incoming call is received as a new incoming call by bulk communication. Determine the destination (step S9
09) (Fourth decision step). If there is no available extension for the necessary channel in step S910, the process of extension busy is performed in step S911, and the flow ends.

In steps S9 and S909, it is determined whether or not there is a vacant extension that can communicate with the required number of B channels, and the called extension number of the identified extension is stored in the caller information station data memory 112 or the ISDN information storage memory. Set to 106. The extension is held until there is an incoming call of the required number of B channels.

Further, at a stage before or after step S2, a representative judgment step of judging whether or not the extension terminal forms a representative may be further provided. in this case,
If no representative is formed, the flow proceeds to flow α. On the other hand, if a representative is formed and bulk connection is performed, step S
It is also possible to shift to 2 or S3, respectively.

Step S9 and / or S909
In the (first and / or fourth determination step), when there are insufficient available extensions or when the number of required channels is not uniform due to time over or the like, a call can be made to arrive at a specific extension of the representative group extension for busy processing. . The extension at this time may be set in advance or the priority may be determined. In this case, the call can be received by a specific operator or a program for automatic response.

The present invention can be mainly applied to various services that require a large amount of data transmission. Applications include, for example, information processing services, search services,
There are an audible display service, an information providing service, a secret transmission service, and the like. The present invention is particularly effective when a representative call is received from a plurality of bulk connection terminals to the center. For example, transmission of security monitoring information of buildings and warehouses, monitoring information for ATMs of securities companies and banks, and the like can be mentioned. In addition, large-capacity and high-quality content information such as music and images, redundant data information in pursuit of security, and the like are required for large-volume data transmission.
